Özet
İngilizce (OpenAlex)
Recently hardfacing by welding has become a commonly used technique for improvement of material performance in extreme (high temperature, impact/abrasion, erosion, etc.) conditions.In the present study, three dierent alloy compositions of the FeNbB were used for hardfacing of the AISI 1020 steel by tungsten inert gas welding process and analyzed.The coatings were produced from a mixture of ferrous niobium, ferrous boron and iron powders in the range of -45 µm particle size with dierent ratio.The coatings' thickness was set to 23 mm on the substrate.Microstructure, phase analysis and hardness of the manufactured hardfacing alloys were characterized.Deposition results indicate good quality thick coating and porosity free of the hardfacings.X-ray diraction analyses showed that the alloyed layers include iron borides, FeNbB and iron phases.It was shown that surface alloyed layer has composite structure including steel matrix and well distributed boride phases.
